Making sure that DateTime properties return DateTimeKind.Utc

Question

Is it possible to define DateTime properties in entity objects that are of Kind == DateTimeKind.Utc by using either the .edmx file, or a t4 template?

When possible using t4, please describe how to change the property. Currently the property gets generated as:

[EdmScalarPropertyAttribute(EntityKeyProperty=false, IsNullable=false)]
[DataMemberAttribute()]
public global::System.DateTime Created
{
    get
    {
        return _created;
    }
    internal set
    {
        OnCreatedChanging(value);
        ReportPropertyChanging("Created");
        _created = StructuralObject.SetValidValue(value);
        ReportPropertyChanged("Created");
        OnCreatedChanged();
    }
}
private global::System.DateTime _created;
partial void OnCreatedChanging(global::System.DateTime value);
partial void OnCreatedChanged();

Yes, it would be possible to use a custom T4 template.

You'd just have to adjust your property setters and getters.

It might be easier to attempt a POCO approach;
